Title: Improvements in machines for manufacturing fluid-filled hermetically-sealed capsules
IPC: A61J3/07
Filed: 1947-07-21
Abstract: 649,772. Reciprocating pumps. SCHERER, R. P. July 21, 1947, No. 19495. Convention date, June 24, 1940. [Class 102(i)] [Also in Group V] A machine for making fluid-filled hermetically-sealed capsules includes a metering device for discharging regulated amounts of fluid between sheets of capsule shell forming material, the device comprising (a) a pair of pumping devices each including a pump chamber and a pump plunger therein, (b) a support for each plunger, (c) means for connecting the supports together, (d) means acting upon the connection to reciprocate the plungers, and (e) means for adjusting the connection to vary the distance between the supports and thus vary the strokes of the plungers in their respective chambers. Five liquidforcing pistons 112 working in pump cylinders 124 are carried by a frame 84 having side arms 88 bridged by a crossbar 96, and five similar pistons 114 working in pump cylinders 126 are carried by another frame 86 that fits telescopically within the frame 84. The frame 86 has two crossbars 92. 94. The two frames are adjustably joined together by a screw-threaded shaft 100 extending between the frame 84 and the crossbar 92. The frames are reciprocated horizontally, to reciprocate the plungers 112, 114, by a crank-shaft 72 carrying a bearing 76 fitting within a yoke 78 guided by arms 80 sliding in bearings 82. As the yoke 78 reciprocates horizontally it engages the crossbars 94, 96 alternately to move the frames 86, 84, respectively. The distance through which the frames, and hence the plungers 112, 114, are moved by the yoke may be varied by varying the distance between the crossbars 94, 96, and this distance is varied by turning a sleeve 10 in which the shaft 100 is threaded. The shaft may be locked in postion by a screw shaft 106 expanding a split section of shaft 100. Liquid to be enclosed in capsule material (gelatin) falls from vat 28 through channels 132 into cylinders 124, 126. and is delivered .by the pistons through channels 134 and pipes 24 to feeder head 26. The blocking and unblocking of the channels necessitated by the facts that both the feed and the discharge channels lead into one end of a cylinder and the two sets of pistons discharge alternately is effected by by a slide valve 136 having passages 133. 135. The pistons are lubricated by pressure oil fed through ducts 212, this oil forming a seal between the cylinders 124, 126 and the atmosphere. The feeder head 26 is carried by two arms 174 pivoted at 172 on the pump unit 22. Specifications 395,546, [Group V], 564,538. 564,539. 564,540. 564,541, [all in Group VI], and 649,773, [Group V], are referred to.

Filed: 1976-05-07
Abstract: 1494274 Measuring the coefficient of friction RUBBER & PLASTICS RESEARCH ASSOCIATION OF GREAT BRITAIN 7 May 1976 [9 May 1975] 19541/75 Heading G1S A known tensile testing machine, Fig. 1, having a slowly movable crosshead 12 supports friction testing apparatus 28 enclosed in a climatic cabinet 30. The test specimen 76, Fig. 2, is fixed to a holder 72 connected to the assembly 20 hanging in a vertical plane and is pressed against non-rotatable friction elements 102, 104 held in a friction block 98 by weights such as 134 hung from a cranked lever 114 pivoted at 116 and provided with a roller 122. The force exerted by the weights is multiplied by a factor X, which is the lever arm movement modified by operational conditions, to give the reaction against the test specimen, and the frictional force is measured by a load cell 14 and recorded on a chart 40, Fig. 1, so that the coefficient of friction may be determined from these two values. In Figs. 4-8 (not shown) the lever 114 is calibrated to compensate for any change in the thickness of the test specimen 76 and deflection of the lever by engaging its roller 122 against a ground glass plate (150) which is deflected by the lever pressure under different weight loads to various angles which are measured by a block (154) and plotted against the lever weights to determine X. The friction force measured by the load cell 114 must however be decreased by the residual friction of the roller 122, and in Fig. 6 (not shown) the deflection measuring block (154) is replaced by a roller carrying block (166) engaging a ground glass plate (170). The friction forces between the bearings of the two rollers engaging the plate cause the cell 14 to deflect and record on the chart 40. This read-out must then be halved to give the friction for the single roller 122. In Figs. 9-12 (not shown) there are described automatic means for removing the pressing force on the test specimen when the specimen has been pulled down to its limit.
